SIMEON B. HENDRICKS, OF ROCKFORD, ILLINOIS, ASSI BrNOR TO THE SKANDIA PLOIV COMPANY, OF SAME PLACE.

HARROW.

SPECIFICATION forming part of Letters Patent No. 399,614, dated March 12, 1889.

Application filed December 17, 1888. Serial No. 293,896. (No model.)

To LLZZ whom if 7120]] concern:

Be it known that I, SIMEON B.IIENDRI(1KS, a citizen of the United. States, residing at Rockford, in the county of lVinnebago and State 5 of Illinois, have invented a certain new and useful Improvement in Harrows, of which the following is a specification.

This invention relates to an improved means of securing together the parts of adjustable 1o lever-harrows; and it consists of certain new and useful constructions and combinations of parts hereinafter described, and pointed out in the claims.

Referring to the accompanying drawings, which form a part of' this specification, Figure 1 is an isometric "iew in detail of a harrow composed of two sections embodying my improvements. Fig. is a detailed plan view of two beams and an end cross-beam of the harrow, a portion oi? one of said beams being broken away to show the manner of connecting the same with an end cross-beam. Fig. 3 is a view of a vertical partial section, through the dotted line X in Fig. 2, of a beam, an end cross-beam, and fastenings for connectii'lg the same together. Fig. i an end view of a barrow-beam and adjust-ing-standard secured together by means of a barrow-tooth and nut.

Like letters of reference indicate correspondin g parts throughout the several views. A is a harrow-beam, preferably cylindrical and tubular in form, provided with transverse holes A, extending therethrough, for admitting barrow-teeth.

B is a barrow-tooth having a horizontal shoulder, B, thereon, and a cylindrical. pertion, l3'-, adapted to be inserted through the holes A in. the beams A and threaded to receive a nut, I3".

0 is an eyebolt threaded. to receive a nut, C, and having the eye C thereof of proper diameter to admit the cylindrical portion 13 ot a harrow-tooth, I3.

D is an end cross-beam having transverse 3 circular openings 1) extending therethrough to admit apart to be described hereinafter.

E is a preferably integral. combined double bushing and washer, consisting of the bushing E, of suitable diameter to readily enter and fit inside of the barrow-beam A, the

washer E projecting from the outside of the bushing D between. the end of the beam A and the end cross-beam, D, and the bushing E", extending through the circular opening I) in the end cross-beam, D.

F is a washer embraced between the nut O and bushing E G is an adjustiiig-standard having a vertical hole, G, extending through the foot G thereof. The standard G is secured to the harrow-beai'n A by means of a barrow-tooth, B, and the nut B, thereby saving a bolt and nut for each standard used in constructing the harrow.

II is an adjusting-beam, which is hingejointed by means of bolts II and nuts H to the adj usting-standards G.

I is a segmentraek secured to the adjustin g-beam H, and I an adj usting-lever secured to one of the harrow-beams A, and also to the adjusting-beam ll, both of which parts and their modes of operation are too well known to require description.

The herein-described means of securing barrow-beams together will be found to be very cheap, convenient, and strong.

I claim and desire to secure by Letters Patent- 1. In combination, in a harrow, a tubular harrow-beam provided with transverse holes A, extending th erethrough, for admitt-ingharrow-teeth, an end cross-beam having transverse openings D therein,tl1e combined double bushing and washer E, the bushing E thereof being inserted into the end of the tubular harrow-beam, the bushing E extending through the opening D in the end crossbeam, and the washer E embraced between the end an eye, C and being inserted through the end cross-beam and combined double bushing and washer E, a harrow-tooth threaded to receive a nut inserted through one of the holes A in the harrow-beam and the eye 0 in the eyebolt, and nuts for securing all of said parts operatively together, substantially as described, and for the purpose specified.

2. In combination, a harrow-beam provided with transverse holes A, extending t-here- I00 transverse openings D therein, the combined: Q

double bushings E, inserted into the ends of r 5 the barrow-beams A and through the end cross-beams, D, the Washers F, the eyebolts G, the teeth B, inserted through the harrowbeams A and eyes 0 in the eyebolts C, the

standards G, the adjusting-beams H, the bolts 20 H, and nuts B C, and H for securing said parts operatively together, substantially as described, and for the purpose set forth.
